<Operation description>
The operation of the home delivery box 1 configured as described above will be described.

  FIG. 2 shows a state in which no luggage is placed on the luggage table 41. In this state, the luggage table 41 is in the upward inclined position, and even if the door 3 is closed in this state, the push-down member 50 is pushed. Since the lowering function unit 53 does not come into contact with the upper edge of the luggage table 41 and enters the lower side of the mounting surface plate 41a through the notch 41c, the luggage table 41 is pressed down by the pressing member 50. Since the latch receiver 22 is located at the latch non-engagement height position where the latch 21 does not engage with the latch 21, the lock is not locked, and the lock cannot be locked unless a load is put in the load storage box 2.

  When no luggage is loaded in the luggage storage box 2, the luggage table 41 is located at the upper inclined position, and the fixed contact piece 61 and the movable contact piece 62 do not come into contact with each other as shown in FIG. In this state, the electric circuit is opened and no current flows through the electric circuit, so that the display lamp 63 is turned off.

  As shown in FIGS. 3 and 4, for example, when the delivery person of the courier places the luggage M on the luggage table 41, the weight of the luggage M placed is sufficient as shown in FIG. 3. Therefore, when the luggage table 41 is completely lowered from the upward inclined position to the horizontal position, and as shown in FIG. May not be completely lowered from the upward inclined position to the horizontal position.

  As shown in FIG. 3, when the luggage table 41 is completely lowered from the upper inclined position to the horizontal position, the latch receiver 22 is moved to the latch engagement height in conjunction with the downward movement of the luggage table 41. As shown in FIG. 6, the pair of locking claws 21c of the latch 21 and the pair of hooks 22c of the latch receiver 22 can be completely engaged.

In this state, when the delivery member performs the closing operation of the door 3, the convex curved surface portion 21 a provided at the right end of the latch 21 shown in FIG. In the collision, the latch 21 is moved leftward by the leftward component of the force acting on the convex curved surface portion 21a from the pair of hook portions 22c at the time of the collision. When the latch 21 is moved beyond the portion 22c in the door closing direction, the latch 21 is moved rightward by the urging force of the compression coil spring 24.
Thereby, as shown in FIG. 8A, the pair of locking claws 21c of the latch 21 and the pair of hooks 22c of the latch receiver 22 are engaged and locked, and the door 3 is closed. The door 3 is automatically locked in the state, and the door 3 is locked by the locking mechanism 20 with respect to the luggage storage box 2 storing the luggage M.

  As shown in FIG. 4, when the luggage table 41 cannot be completely lowered from the upper inclined position to the horizontal position, that is, when the luggage table 41 is located between the upper inclined position and the horizontal position. As shown in FIG. 7, the latch receiver 22 is located between the latch non-engagement height position and the latch engagement height position. Although the gap provided for allowing play in the height direction between the pair of claw hooks 22c of the receiver 22 is reduced, the pair of locking claw portions 21c and the pair of claw hooks 22c are not engaged. In this state, or in a state where the pair of locking claw portions 21c and the pair of claw hooking portions 22c can be engaged, the engagement dimensions are small and the engagement is insufficient.

When the delivery member performs the closing operation of the door 3 in such a state, as shown in FIG. 4, the push-down function unit 53 of the push-down member 50 comes into contact with the front edge of the placing surface plate portion 41 a and tilts. The luggage carrier 41 is pushed down by the downward component of the force acting on the front edge from the surface 55, and in conjunction with this, the latch receiver 22 is moved to the latch position as shown in FIG. The pair of locking claw portions 21c and the pair of claw hook portions 22c are completely engaged with each other.
Thus, even when the weight of the load M placed on the load table 41 is insufficient and the latch receiver 22 cannot be lowered to the latch engagement height position where the latch 21 is completely engaged with the latch 21, the door 3 is closed. The luggage table 41 is pushed down by the pushing member 50, and in conjunction with this, the latch receiver 22 is completely pulled down to the latch engagement height position.

Are in contact with each other, the electric circuit is closed and a current flows through the electric circuit, so that the display lamp 63 is turned on.

  When the receiver of the luggage confirms that the luggage is contained in the luggage storage box 2 by turning on the display lamp 63, the luggage receiver inserts a locking key (not shown) into the key insertion slot 33, and rotates the locking key to the right to operate the latch. As shown in FIGS. 9A and 9B, the door 3 is opened by opening the door 3 and the baggage in the baggage storage box 2 is taken out.

<Explanation of operation and effect>
According to the delivery box 1 of the present embodiment, when the luggage is placed on the luggage storage 41, the luggage storage 41 is moved down by the weight of the loaded luggage, and the luggage placed on the luggage storage 41 is removed. When removed, the luggage table 41 moves up, and in conjunction with this, the latch receiver 22 moves up and down between a height position where it does not engage with the latch 21 and a height position where it engages with the latch. A function that cannot be locked unless luggage is loaded in the luggage storage box 2 and can be locked when luggage is loaded can be achieved with a simple and inexpensive configuration.

  Further, when the door 3 is closed with the luggage placed on the luggage storage 41, the pressing member 50 for pushing down the luggage storage 41 to a predetermined position is disposed on the door 3, so that the luggage storage 41 is provided. Even if the luggage table 41 is not fully lowered from the upwardly inclined position to the horizontal position due to insufficient weight of the luggage placed on the luggage table, the luggage table 41 is pushed down by the pressing member 50 when the door 3 is closed. As a result, the latch receiver 22 is pulled down to the latch engagement height position, so that even if the load is relatively light, it can be ensured that it can be locked.

  In addition, it is possible to know from the lighting state of the display lamp 63 that luggage is contained in the luggage storage box 2, and it is possible to know that there is no luggage in the luggage storage box 2 by extinguishing the display lamp 63. Since it is possible to know, the presence or absence of luggage in the luggage storage box 2 can be easily known only by visually checking whether the display lamp 63 is on or off without opening the door 3.

  As described above, the home delivery box of the present invention has been described based on one embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration is appropriately changed without departing from the gist thereof. Is what you can do.

In the above-described embodiment, as shown in FIGS. 11A and 11B, the presence / absence of luggage in the luggage storage box 2 is determined by turning on / off the display lamp 63 provided in the electric circuit. However, the present invention is not limited to this. For example, as shown in FIGS. 12A to 12D, the magnetic body 71 and the door 3 provided on the luggage storage box 2 side are used. Detecting means 70 for detecting whether or not a load is placed on the load table 41 based on a suction / non-adsorption state with the magnet 72 disposed on the side, and a display for indicating a detection result of the detection means 70 The presence / absence of the baggage M in the baggage storage box 2 may be known by using a member including the display member 73 functioning as a means.
Note that there is also an embodiment in which the magnet 72 is provided on the luggage storage box 2 side and the magnetic body 71 is provided on the door 3 side.

<Description of detection means>
The detecting means 70 is provided to extend to a separate interlocking member 75 connected to the upper end side of the upper extension 45a of the interlocking member 45 and to a side where the display member 73 is disposed at the upper end of the interlocking member 75. An arm 76, a magnetic body (for example, an iron piece) 71 mounted on the distal end of the arm 76, and a magnet mounted on the display member 73 so as to face the magnetic body 71 and be positioned below the magnetic body 71. 72.
In the detecting means 70, as shown in FIGS. 12A and 12B, when the luggage table 41 is in the upwardly inclined position, depending on the attractive magnetic force acting between the magnetic body 71 and the magnet 72, the display member may be displayed. When the magnetic body 71 is located at the non-suction height position where the 73 is not lifted and the luggage table 41 is at the horizontal position, the display member 73 is pulled up by the attractive magnetic force acting between the magnetic body 71 and the magnet 72. The amount of change in the distance between the magnetic body 71 and the magnet 72, the strength of the magnet 72, and the like are set so that the magnetic body 71 is located at the suction height position.

<Description of display member>
The display member 73 includes, for example, a display plate 77 on which characters “received” are written, and a pair of support rods 78 that are vertically provided on both sides of the display plate 77. The closed face plate is moved so that the display plate 77 moves between a display height position where the display plate 77 faces the display window 79 provided in the display window 79 and a non-display height position where the display plate 77 is hidden below the display window 79. It is vertically movably supported by a support guide member 80 attached to a predetermined position on the back side of the portion 3a.

When the luggage stand 41 moves up and down between the upper inclined position and the horizontal position, the magnetic body 71 provided via the interlocking members 45 and 75 and the arm 76 interlocks with the luggage stand 41, and the non-suction height position is set. Up and down between and the suction height position.
When the luggage table 41 is at the upper inclined position, the magnetic member 71 is located at the non-adsorption height position, and the display member 73 is not pulled up by the attractive magnetic force acting between the magnetic member 71 and the magnet 72. Since the display member 73 is located at the non-display height position, the word “received” does not appear on the display window 79 as shown in FIG. You can know that is not.
When the luggage table is in the horizontal position, the magnetic member 71 is located at the suction height position, and the attracting magnetic force acting between the magnetic member 71 and the magnet 72 raises the display member 73 so that the magnetic member 71 is magnetized via the magnet 72. Since the display member 73 is positioned at the display height position by being absorbed by the body 71, the characters “received” appear in the display window 79 as shown in FIG. Can be found that is placed.

  In this way, the character “Received” is displayed on the display window 79 by the display member 73, so that it is possible to know that the luggage is contained in the luggage storage box 2. Is not displayed in the display window 79, it is possible to know that there is no luggage in the luggage storage box 2. Therefore, the luggage storage box can be checked only by visually checking the display window 79 without opening the door 3. It is possible to easily know the presence or absence of the baggage in 2.

When the door 3 is opened in a state where the display member 73 is attracted to the magnetic body 71 via the magnet 72, the magnet 72 is forcibly slid with respect to the magnetic body 71 to be separated from the magnetic body 71. Since the magnetic force attracted to the magnet 72 does not act, the display member 73 naturally descends by its own weight, and the display member 73 is automatically positioned at the non-display height position.
Then, after removing the luggage placed on the luggage storage table 41 and closing the door 3, the luggage storage table 41 is in the upper inclined position and the magnetic substance 71 is located in the non-adsorption height position. Due to the attractive magnetic force acting between the magnetic body 71 and the magnet 72, the display member 73 is not pulled up, the display member 73 remains at the non-display height position, and the display window 79 displays Does not appear, and it can be confirmed by visual observation of the display window 79 that the luggage is not placed on the luggage table 41.
